The Jāpu Sāhib serves as a general invocation at the beginning of the Dasam Granth Sahib. It has parallels with the Jap of Guru Nanak, the first composition in the Adi Guru Granth Sahib. Guru Nanak bows to Vahiguru, ādesu tisai ādesu, and this same devotion is continued on by the Tenth Nanak - Guru Gobind Singh.
